BMW had said in 2012 that it would use carbon fiber in the structure of a new 7-Series, following reports that Mercedes-Benz will build a version of its next-generation E-Class with a carbon-fiber structure that could save as much as 770 pounds.

That car has not yet been released, but we can expect additional details this year or next.

Following the industry trend, the new 7-Series will use a number of downsized and turbocharged engines, an eight-speed automatic transmission.

While the company didn't say anything about a plug-in hybrid model, the lineup is bound to include one or more--possibly using the company's next-generation Power eDrive system.

Competitor Mercedes-Benz already offers a plug-in hybrid version of its own S-Class large sedan, and is steadily spreading the system across other vehicles in its range.

Meanwhile, the Cadillac CT6 plug-in hybrid model launched today at the Shanghai Motor Show uses a far larger battery pack and will likely provide far higher electric range than any of the German competitors.
